Comparison of the timing feature in Cyg X-1 to similar data for the low-mass X-ray binaries MAXI J1820+070, MAXI J1348−630, and AT 2019wey. In all four observations, a reduction of L₂ at low energies, a time lag jump between soft (0.5–1 keV) and hard (2–4 keV) photons, and a coherence drop in the overlap region of the Lorentzians can be seen. The similarity of the data suggests that the timing feature is a ubiquitous property of accreting black hole binaries.
